The retreat is further enhanced with a private sauna and a sensational Roman rotunda spa. Designed for large-scale entertainment, the Great Room can easily be transformed into a Grand Ballroom for significant events and celebrations. Multiple French doors open onto a Grand Terrace with a central fountain, overlooking the resort-style pool, spa, and cascading waterfalls.
